-- CO2 levels, as skipdog points out, are at their highest level in hundreds of thousands of years.



So what? A couple of hundred thousand years are a blip in time. CO2 levels have been higher in the past than they are now. And even so, there is no documented evidence that higher CO2 levels today are creating a warmer climate than can be explained by normal cyclical temperature swings.

Is human-generated CO2 contributing to global warming? Absolutely.



"Global warming" is a myth.

Quote:

Although I can understand people still arguing the causes of global warming, the fact that it is occurring is grounded in a lot of observational evidence.



How far back you wanna go? Is the earth warmer than it was 10 years ago? Does that consitute "global warming"? What about 700 years? It's documented that the earth was warmer in the 13th century than it is was in the 20th century. Is that "global cooling"? Fact is, there is no discernable pattern of temperature shift over the long term (100-500 million years).
